4 Claims. (01. 88- -24) (Granted under'the act of 'March 3, 1883, as amended April 30, 1928; 370 O. G. 757) The invention described herein may be manufaotured and used by orfor the Government for governmental purposes, without the payment to me of any royalty thereon. v i

This invention relates to a combination copying and specimen holding stand for photographic use.

Photographing certain objects of steel. particularly metallurgical specimens. with a-horizontal camera is a tedious, time consuming procedure because of the difiiculty encountered in making a suitable set-up. The specimen must be carefull supported onits side and if a plurality of specimens are to be photographed simultaneously they must be carefully supported on top of each other by props and then the props masked out. Where the studio has in addition considerable copying of drawings and other prints with the same horizontal camera, considerable inconvenienc'e and loss of timeis experienced because of entirely different set-ups necessitated by photographing this work of an entirely different character. If a combination stand which comprises a copying frame and a rapid set-up holder for small steel specimens could be provided much timecould be saved.

Accordingly, it is an object of this invention to provide a combination photographic stand having both a copying frame and a specimen holder for alternate use with the same camera.

A particular object of this invention is to provide a. specimen holder on which iron or steel specimens may be rapidly mounted for photographing by ahorizontal camera.

Thespecific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of'a, preferred embodiment as shown] in the accompanying drawings in which: I

Fig. 1 is a front elevational view of the combination stand. v

Fig. 2 is a left side elevational view of the combination stand as viewed in Fig. l.

Fig. 3 is a top elevational view of Fig. 1.

"Fig. 4 is an enlarged partial cross sectional view taken along the plane 4-4 of Fig. 2 showing the method of rotatably securing the turntable to the base. I I

In the accompanying figures wherein like characters refer to similar parts there is shown a circular turn table Two upright tubular supports.

2 and 3are secured near oneedge of turn table I by welding orby suitably fastened pipe flanges 4 and 5. A magnetic chuck 6 of the type'commonly used on surface grinders and having a, fiat active surface 6a is pivotally supported by a yoke 1. The yoke 1 having upstanding arms 1a and 1b may be made of suitable strap material bent into a broad U-shape as shown in Fig. 1. Fixed threaded studs 8 and 9 centrally located at each end of magnetic chuck 6 are provided for pivotally mounting the chuck 6 in the yoke 1,. Each stud 8 and 9 projects through suitable holes in the upstanding arms 1a and 1b of the yoke 1. A crank II] is securely fastened to the stud 8 on the outside of the arm 1b. on the stud outside of the arm 1a a binding nut is provided to lock the magnetic chuck 6 in any desired position in the yoke 1. The crank I0 permits manual rotation of the magnetic chuck 6 to such position. Additional clamping means is provided by a winged bolt H which engages a slot l3 in the arm 1a and engages a suitably threaded hole in magnetic chuck B. It should be understood that the magnetic chuck may be either the permanent magnet or electromagnetic type. 7

Guide members M and |5 are secured to the bottom of yoke 1 as by welding and are so positioned that they will slidably engage the tubular supports 2 and 3. The guide members l4 and I5 are then inserted in the tubular supports 2 and 3. For ease and convenience in. raising the magnetic chuck 6 to any desired height, a hydraulic lift I5 is provided. For the hydraulic lift l6 any hydraulic jack of the type used for automobiles may rbe utilized. If desired the lift I6 may be removably secured to the turn table I and to yoke 1 to provide a readily replaceable unit. A lever I1 is provided to actuate the hydraulic lift l6 and a valve I8 is provided to release the lift for lowering the chuck 6. The piston |9 of the conventional lift |6 may be lengthened to obtain the maximum height of chuck 6 desired. It is thus apparent that by the use of the hydraulic lift IS the magnetic chuck 6 may be easily and conveniently raised to any vertical position desired within the limit of extension of the hydraulic lift.

Opposite the supports 2 and 3 and in a plane parallel to those supports there are provided two other upstanding supports 2| and 22. The supports 2| and 22 are preferably formed from angle iron and are secured to a stiffening member 23 preferably by welding. The supports 2| and 22 are slightly higher than the lowest position of the magnetic chuck 6. A copying easel 24 is pivotally mounted between the upright supports 2| and 22. The easel 24 comprises a backing board 25 which is secured to brackets 26 and 21 by suitable screws. A conventional copying frame 28 is mounted on the front of backing board 25 by a long piano type hinge 29 and is fastened at its upper edge by two spring catches 30. A long rod 3| threaded at each end is placed near the top of the upright supports 2| and 22 in suitablenut 33 suitably secured against tiu'ning while on the other end of rod 3| a knurled locking nut 34 is provided. By tightening the locking nut 34 the easel 24 may be secured in any position desired. However, as it is generally necessary to use the easel in a plane perpendicular to the horizontal axis of the optical center of the horizontal camera lens a suitable stop 35, which may be a short bolt-like member, is secured to bracket 26 so that when the easel is tilted upwardly until stop 35 strikes the support 2| the easel will be in a vertical position. For placing copy in the copying frame 28 the easel may be lowered to a horizontal position where it will rest on the magnetic chuck which in its lowest position serves as a suitable stop. Thus it will be readily seen that copy may be ver conveniently placed within the copying frame prior to raising the frame to the working position.

The upright supports 2, 3, 2|, and 22 are further supported for rigidity by cross braces 36 and 31 provided on opposite ends of the combination stand. The turn table I is mounted on three evenly spaced casters 48. The casters 48 in turn rest on a circular base 4| of a carriage 42. A bolt 43 (Fig. 4) passing through the centers of turn table and the base 4| is secured in such a manner as to permit only rotational movement of turn table about base 4|. Carriage 42 com prises the base 4|, to which there are secured by parallel angle irons 44, two parallel axle supports 45 mounted perpendicularly to base 4|. The angle irons 44 which support the members 45 are preferably welded to the base 4| and the supports 45. Mounted near the ends of support members 45 are two axles 46. Flanged wheels 4'! are provided on each end of axles 46 and are suitably secured thereto. The flanged wheels 47' are placed upon two parallel rails 48, which may be of any convenient length, and from the bed for the combination stand and camera carriage. Thus with the combination stand so mounted it is a relatively easy procedure to bring the subject matter on the stand to be photographed within focusing range of a fixed position horizontal camera by merely rolling the stand along the rails 43.

To photograph any iron or steel specimen" capable of being held by the particular magnetic chuck 6 utilized, the object has merely to be located on the face a of the magnetic chuck while such face is in a horizontal plane where it will be held by the magnetic forces of the magnet. It should be mentioned here that by suitable steel adapters other non-metallic objects maybe conveniently held on the magnetic chuck. A sheet of white paper inserted between the specimen and the chuck face provides a fine background. The chuck is then pivoted so that the face 6a' is vertical and is clamped in such position by screws II and I2. The object held by'the magnetic chuck may be quickly and conveniently raised to the optical center of the camera lens by means of the hydraulic lift I6 which raises the magnetic chuck 6 to the proper height. If it is desired to change the plane of the magnetic chuck from the perpendicular to any other position in order to bring out more detail in the specimen being photographed, it is only necessary to unloosen the binding screws II and I2 and their turn the magnetic chuck by means of the crank ID to the desired position and then again clamp the binding screws II and I2.

Focusing the camera is greatly facilitated because the combination stand is mounted on rails. Thus the stand can be readily moved nearer or farther away from a fixed camera until the image to be photographed comes roughly into focus on the ground glass of the camera. Finer focusing adjustments can then be made on the camera itself. To use the copying stand, the combination stand is rotated on its axis about the camera until the easel is at right angles to the optical center of the camera lens. Copy placed in the copying frame of the easel is then photographed in much the same manner as photographing a specimen attached to the magnetic chuck. The same adjustments may be made for the easel 24 as for the magnetic chuck if desired. It should be noted that a set-up on the magnetic chuck need not be disturbed if it is necessary to do a rush job on the copying stand or vice versa.
